NANOTECHNOLOGY

What is nanotechnology?

Nanotechnology is the study of matter on a molecular scale that can be applied to all fields of science. Nanotechnology is science technology and engineering conducted at 1 to 100 nanometers.

Application of Nanotechnology

Nanotechnology is used in every field of science but it is also used in every day life.
  1. Tissue Engineering: Nanotechnology can reproduce of repair damaged tissue. It can also lead to cell based therapeutics for the prevention, diagnosis, & treatment of diseases.
  2. Clothing: Nanoparticles organize themselves in clothing to form a coating over the material to repel liquids taking dirt with them.
  3. Cosmetics: Nanotechnology is used in sunscreens. The nanoparticles of titanium dioxide and zinc oxide are used to block UV rays.

Uses of Silver Nanoparticles

Silver Nanoparticles are involved in the killing of bacteria
  1. Drug Resistence: Silver Nanoparticles eliminate bacteria and viruses that an antibiotic normally would not.
  2. Water Purifiers: Silver Nanoparticles eliminate bacteria in water
  3. Clothing: Silver Nanoparticles cling to the fabrics to prevent germs and viruses from penetrating it

Drawbacks to Silver Nanoparticles

  • Silver Nanoparticles have be known to stop the reproduction of good bacteria and in some studies have been shown to kill good bacteria that cleans our water resoivors. It can also kill bacteria and harm living organisms because the waste is released into the water system.
